Power 400 Watt Class-ad 4-Channel Amplifier

The Power T400X4ad is an ultra-compact, high efficiency 400 Watt 4-channel amplifier. Features multi-impedance Constant Power, input/output clip detection, top mounted controls and dual fan forced induction cooling. Perfect for hybrid, electric, small cars, trucks, motorcycles, and side-by-side UTVs. Rockford Fosgate proprietary Class-AD technology 4/2 Ohm muti-impedance Constant Power Differential inputs with high level auto turn-on feature 8 AWG power/ground connector w/ upgraded RCA connectors Remote-Out feature when using high level inputs 2/4 channel input switch 4 Ohm bridged capable C.L.E.A.N. input/output clip detection and indicator LEDs Top mounted controls Dual fan cooled Real time thermal sensing Dual extruded heat sinks Discrete surface mount technology The Power T400X4ad 400 Watt 4-channel ultra-compact, amplifier is built on Rockford Fosgate’s proprietary Class-AD technology, featuring Constant Power to produce the same output at both 4-Ohm and 2-Ohm impedances. Flexible vehicle integration enabled through low-level and high-level inputs with auto turn-on. Top mounted controls allow easy access to built-in crossover and C.L.E.A.N. input/output clip detection circuits. The 3-stage thermal lock extrusion with dual fan forced induction keeps everything cool while real-time thermal/protection schemes safeguard the amplifier.
